CAP-FASTENING FOR VESSELS.

SPECIFICATION forming part of Letters Patent No. 784,513, dated March'7, 1905.

Application filed June 15,1904. Serial No. 212,663.

To @ZZ 707mmJ it mfay concern.'

Be it known that I, AUGUSTUS BRocKEL- BANK, a subject of the King ofGreat Britain, and a resident of Ossining, in the county of lVestchesterand State of New York, have invented anew and Improved Cap-Fastening forVessels, of which the following is a full, clear, and exact description.

The purpose of my invention is to provide a construction for the neck ofa bottle or like receptacle and a construction of cap for the same whichwill enable the cap or cover to be quickly placed in closed position onthe receptacle and turned to a locking engagement with the neck of saidreceptacle and further turned in the same direction to provide for aconvenient removal of the cap or cover from the receptacle.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the Vfigures.

Figure 1 is a perspective view of a simple form of cap or cover for thereceptacle. Fig. 2 is a perspective view of the upper or neck portion ofa receptacle to which the cap or cover is to be attached. Fig. 3 is avertical section through the neck portion of the receptacle shown inFig. 2 and likewise a vertical section through the cap or cover shown inFig. 1, the latter being in locking position with the neck of thereceptacle. Fig. 4 is a horizontal section taken practically on the line4 4 of Fig. 3. Fig. 5 is a bottoni plan view of a cap or cover slightlydifferent in construction from that shown in Fig. 1, and Fig. 6 isalvertical section through the cap or cover shown in Fig. 5.

A represents a receptacle which is shown as a bottle having a neck A',and at a suitable distance below the mouth 10 of the neck A an exteriorendless groove 11 is produced,

and opposing recesses 12, preferably of semicircular or segmental form,extend exteriorly from the .mouth 10 of the receptacle to a connectionwith the groove 11, as is best shown in Fig. 2. The groove 11 is in twospiral or inclined sections c and a', as is shown in full lines in Fig.2 and indicated in dotted lines in Fig. 3, the inclinations of whichsections of the groove 11 start from a terminal at the recesses 12 inthe mouth portioii 10 ofthe receptacle. In the further construction ofthe grooved portion of the neck A at the opposing lowest port-ions ofthe sections a and a of the groove 11, or those portions which arefarthest from the mouth 10 of the receptacle, semicircular or segmentalrecesses 13 are formed in the back wall of the said exterior groove 11,as is especially Shown in Figs. 2 and 4.

B represents a simple form of cap or cover for the mouth of thereceptacle A, which cap or cover is provided with a downwardly-extendingmarginal i'lange 14, of spring material, and at diametrically oppositesides of the cover-flange 14 opposing circumferential cuts 15 are made,forming thereby opposing spring-tongues C, constituting an integralportion of the aforesaid cap or cover, and these tongues C are made toincline more or less downward in direction of their free ends and, as isshown in Fig. 1, are provided at their free ends withinwardly-projccting semicircular lugs 16. Vhen the cap or cover isreplaced upon the receptacle, the lugs 16 of the cap are fitted in therecesses 12 at the mouth 10 of the receptacle, and as the cover or capis pressed down the lugs enter the groove 11 in the neck of thereceptacle. Upon turning the cap or cover B the lugs 16 on thespringtongues C will find seats in the recesses 13 in the back wall ofthe groove 11 in the receptacle and will at suoli time hold the cap orcover in place, and such Cap or cover' B will be drawn sufficientlydownward to cause an inner packing or washer l), carried by the saidcap, to be tightl)7 clamped against the upper surface of the mouth ofthe receptacle, thus providing for the receptacle being tightly andhermetically sealed. Then the cap or cover is to be removed, it isturned in the same direction as before, and as the lugs 16 of thespring-tongues C are of segmental form, and likewise the recesses orpockets 13 receiving them, the lugs 16 readily enter and readily leavethe said recesses or pockets. When the lugs 16 on the spring-tongues oithe cap or cover B are opposite the exterior recesses 12 at the mouth ofthe receptacle A, the cap or cover B may be instantly and readilyremoved from the receptacle.

ln Figs. 5 and 6 l have illustrated a slightlydifferent form of cap orcover; but the same principle is preserved as that shown in Fig. 1. Thecap or cover B shown in Figs. 5 and 6 is provided with adownwardly-extending flange 14a, but at opposite points in the saidilange 14a pockets 17 are formed, and in these pockets the coiled ends18 of springtongues C are held, and the bodyV portions of these tonguesextend in opposite directions below the said cover, having a downwardinclination, as is shown in Fig. 6, corresponding to the downwardinclination of the tongues C shown in Fig. 1. Each spring-tongue C isprovided at the inner portion of its free end with a segmental lug 19,and the lugs 19 of the spring-tongues C correspond to the lugs 16 on thespring-tongues C in the form of cap or cover shown in Fig. 1.

The method of applying the cap or cover to the receptacle whenconstructed as shown in Figs. 5 and 6 is the same as when the cover ismade as shown in Fig. 1, and likewise the two forms of covers areremoved from the recIeIptacle in the same manner.

aving thus described my invention, l claim as new and desire to secureby Letters Patent- 1. In cap-fasteners for vessels, a cap havingspring-tongues forming a part of its lower section, the tongues havinglocking-lugs at .the inner faces of their free ends.

2. A cap-fastener for vessels, consisting of a cap, opposingspring-tongues secured at one of their ends to the ilange portion of thecap, the tongues being inclined downwardly in direction of their freeends and provided at the inner faces of their free ends with segmentallugs.

3. A vessel provided with an exterior groove at its neck, recessesleading from the mouth of the vessel into the said groove, recessesformed in the back wall of the groove, all the recesses being ofsegmental form, a cap or cover for the mouthportion of the saidreceptacle, and spring-tongues carried by the said cap or cover,provided at their Jfree ends with segmental lugs on their inner faces,which lugs are entered into the said groove through the mouth-recessesof the receptacle and are adapted to iit in the recesses in the backwall of the groove in the neck of the vessel.

4. A receptacle provided with an exterior groove at its neck portion andrecesses leading from the mouth of the vessel to the groove, the saidgroove being inl two spiral sections commencing and terminating at thesaid recesses at the mouth, each section of said groove being providedwith a recess in its rear wall, a cap or cover for the said vessel, andspring-tongues forming a portion of the cap or cover, having lugs attheir free ends adapted to pass through the recesses at the mouth of thevessel to enter the recesses in the back wall of the groove in thevessel.

5. A vessel provided with an exterior groove at its neck portion,segmental recesses extending Jfrom the mouth of the vessel into thegroove, said groove being in two oppositely-inclined sections, theinclinations starting from and` terminating at said recesses, eachsection of the groove being provided with a segmental'recess in its rearwall, a cap or cover for the vessel, spring-tongues forming a portion ofthe flange oi" the cap or cover, the tongues being inclined downward indirection of their free ends, and segmental lugs formed at the innerfaces of the free ends of the said spring-tongues, which lugs areadapted to be seated in the recesses in said groove.

In testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.

AUGUSTUS BROCKELBANK.
